I bought these for my husband both in black and white which is his normal size 11. They fit perfectly. Yes, some of the previous comments are correct, they are a bit more difficult to put on than 'regular' running shoes due to the tongueless design. It's not that difficult, though, and believe me, if it were, my husband would be the first to complain. He says the shoes are extremely comfortable for running, walking etc. They also look very nice on the foot, not clunky and clunky like some running shoes.
